Make a component that accepts child elements

Is this really how to do it?

1. Create a slot component
2. Put the slot component in your component
3. Apply an “instance swap” property to the slot component
4. Create another component, what you want to put in the frame component
5. Create an instance of your frame component and swap the slot with the component from step 4

There is no way to make slots in Figma without some workarounds. Vote here: Add a "slot" functionality to components or Fully Editable Component Instances (someone needs to merge these)
